Prince Harry has been approached to star in a porn film after nude shots in Las Vegas

The British royal has allegedly been offered a sum of $10 million to appear in an adult movie called 'The Trouble With Harry' based on his naked antics in Las Vegas.

Vivid Entertainment's Steve Hirsch has sent a letter to the royal Palace in London detailing his full offer to the "party Prince", which is said to include full-frontal sex scenes that show off "little Harry".

According to TMZ, Steve wrote: "We assure you the sex will be well-scripted, and the crown jewels will not be 'minimized' in any way."

The 27-year-old fun-loving royal caused a stir when nude photographs of him playing a game of strip-billiards were published online this week.

He has reportedly since been given a "stern telling-off" from the royal family and was ordered to make a public apology.

A source told Radar Online: "Harry regrets the embarrassment he has caused the royal family around the world and plans on apologizing for his antics.

"He got a stern telling-off from his father, Prince Charles, as well as the Queen, who reminded him of his responsibilities as a member of the Royal Family."

The Prince was last forced to issue a public apology in 2005 after he attended a costume party dressed as a Nazi.

Harry - who is third in line for the British throne - is due to make a statement before London's Paralympic Games on August 29.
